FILM HOLDER.

Application filed March 8,

To all whom it may concern:

Be it known that I, HENRY Bunsen, Jr., a citizen of the United States,and a resident of the city of Portland, county of Multnomah, and Stateof Oregon, have invented a certain new and useful Improvement in FilmHolders, of which the following is a specification.

My invention relates to means for holding photographic films in such wayas to facilitate their draining and drying.

The object of my invention is to provide means which will not onlysecurely hold the film at its four corners, but which embody no partstending to cause the draining liquid to adhere and collect on the filmsupporting parts of the holder; and in this way to promote the effectivedraining of the liquid.

It is further the object of my invention to provide holding means whichwill not tend v to tear the film, at the same time firmly holding thelatter. It is further my object to provide a holder having only deviceswhich are simple in construction, and simple and convenient tomanipulate. V

The above enumerated and incidental features I attain by the deviceillustrated in the accompanying drawings, in which:

Fig. 1 is a front elevation of my holder showing the same as being usedfor supporting a film by its four corners; two corners of the film beingbroken away so as to disclose more clearly the holding means;

' Fig. 2 is an elevation looking at the right hand side of my holder; V

Fig. 8 is a perspective detail of parts which would be seen by lookingat my holder approximately at an angle indicated by the arrow 3 of Fig.1; and

Figs. 1 and 5 are details of the right hand lower corner of my holder,and of the means there provided for holding a corner of the film, andthe means by which the holding means are arranged in their active andinactive positions; their active positions being shown in Fig. 4, andFig. 5 showing the same means as they appear when arranged in theirinactive positions.

My invention comprises a rectangular supporting frame a which may bemade of a piece of wire bent as shown. The upper ends a of the frame areunited by a cross bar 7), and said upper ends may be bent outward asshown by c. A hook (Z is affixed to the bar 6. On each of the framesides a is afiixed a spring arm 6 preferably constructed asSpecification of Letters Patent.

shown, and firmly mounted on the fiat middle parts a? of the frame sidesas shown in Figs. 1 and 2, thus each spring-arm has opposite free ends 6and c Said free ends are bent inwardly as at f, and downwardly as at gin Fig. 3, and the downwardly bent extremity g terminates in ashouldered pin-point h.

'At the four corners of the frame a are provided rigid ledges i, and onsuch ledges are provided film-supporting protuberances j which arepreferably made hemispherical. It is on these supporting protuberances jthat the corners of the film are rested, and these supporting surfacesare made hemispherical so as to recede abruptly from the film surfaceresting thereon, and thus avoid having two parallel surfaces betweenwhichthe liquid may adhere and collect.

The film supporting protuberances j are provided with cavities 7c toreceive the shouldered pin-points of the free ends 6 and c of saidspring arms.

In order to hold said free ends of the spring arms in their out of theway or inactive position, and also so that the pin-points thereof willbe placed in registration with the cavities k, I provide each of theledges i with rests Z having a notch m adapted for supporting the freeends of the spring arms in their inactive position, and another notch 12adapted to hold said free ends in their active position as mentioned; sothat the pinpoints h of said free ends of the spring-arms J maybepunched through the film, and thus the latter may be held securely inplace by its four corners. The pin-points h are shouldered so as toavoid making larger perforations in the corners ofthe film thannecessary for holding the same securely in place.

In order to facilitate the placing of the film on the supportingsurfaces is I provide each of the ledges z' with guide lugs 0 and p; andit is to be noted that these guide lugs do not connect, thus avoidinganyangular surfaces which would tend to cause the adhering or collectingof the liquid draining from the film.

The ledges i, and their parts, are so constructed that they may bereadily stamped out of metal, thus facilitating the inexpensivemanufacture of my device.

The operation of securing the film in place on my holder consists firstin placing the film within the, guide lugs 0 and p;

having previously arranged the free ends of the spring arms intheir'inactive position; said free ends are then lifted into theiractive positions and the corner of the film. V The drawings are intendedto represent a. convenient mode of carrying my invention into practice.r
